Cleaning of the stator, rotor,  exciter and diode bridge

The insulating components and the impregnation system are
not at risk of damage from solvents (see the above list of
authorised products).

Avoid letting the cleaning product run into the slots. Apply the
product with a brush, sponging frequently to avoid
accumulation in the housing. Dry the winding with a dry cloth.
Let any traces evaporate before reassembling the machine.

4.2.7 -  Mechanical servicing

Cleaning the machine using water or a high-pressure
washer is strictly prohibited.
Any problems arising from such treatment are not
covered by our warranty.

The machine should be cleaned with a degreasing agent,
applied using a brush. Check that the degreasing agent will
not affect the paint.
Compressed air should used to remove any dust.
After cleaning the alternator, it is essential to check the
winding insulation (see sections § 3.2. and § 4.8.).

4.3 -  Fault detection

If, when commissioned, the alternator does not work
normally, the source of the malfunction must be identified. To
do this, check that :
- the protective devices are fitted correctly
- the connections comply with diagrams in the manuals
supplied with the machine
- the speed of the unit is correct (see nameplate).
Repeat the operations defined in section 3.
